I tried doing that aswell as trying it out with a spare battery, the computer also does not recognize the blackberry anymore. The battery says 3.7V on it but the charger says 5V, is this what the problem is, did i fry my phone? I read the people use their razr chargers to charge the BB just fine and i know the razr charger is 5v so if they didn't fry theirs what happened to mine?
